IS Document Structure
The FIX message document structure varies according to the FIX message version and the message type. For example, the structure of the message header for version 4.0 is different than for version 5.0. Similarly, the structure of the header and trailer is the same for all messages of the same version, but the application message structure varies according to the message type.
Each IS document contains the following fields as indicated by the corresponding IS document type:
IS Document Field
Description
Header
Contains the FIX message header fields.
ApplicationMessage
Contains the FIX application fields.
Trailer
Contains the FIX message trailer fields.
unIdentifiedFields
Contains fields that cannot be identified in the incoming message because they are not part of the FIX specification. This field is only populated for incoming messages. It is not used when sending a FIX message.
